The Missile Defense Agency (MDA) of the Department of Defense is seeking information from qualified contractors regarding the Advanced Object Classification (AOC) 1.1, a software upgrade aimed at enhancing the classification of objects during the midcourse phase of ballistic missile flight. This upgrade will build upon the advancements made in AOC 1.0, incorporating additional algorithm updates and a flat-file classification database to allow for rapid reconfiguration in response to emerging threats without necessitating software recompilation. The AOC 1.1 is critical for improving object classification accuracy against complex threats, utilizing machine learning techniques while requiring no changes to existing radar hardware or interfaces. Interested parties must submit their responses by close of business on October 17, 2025, and can direct inquiries to Brandon Smith or Lashonda Fletcher via the provided contact information.
